摘　　要：素填土地基被扰动后存在一定的土体工程应用缺陷性,结合桂林市恭城县某工程实例,采用理论公式计算法、实际观测、FLAC3D数值模拟三种方法对素填土地基沉降进行研究,研究表明:理论计算值较大,数值模拟值次之,数值模拟与实际观测沉降量值接近,误差较小,可较好地预测素填土地基沉降变化规律。The application of soil engineering after soil foundation disturbance exhibits certain deficiencies.By utilizing an engineering case study in Gongcheng County,Guilin City,this research investigates the settlement of the soil foundation through three approaches:theoretical formula calculation,actual observation,and FLAC3D numerical simulation.The findings indicate that the theoretical calculation yields higher values compared to the numerical simulation results.However,both the numerical simulation and actual observation demonstrate similar settlement values with smaller errors,thereby offering improved prediction capabilities regarding changes in soil foundation settlement.
